BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a shoe or a shoe sole, and more particularly to a shoe or a shoe sole having one or more detachable or changeable light devices.

[0003] 2. Description of the Prior Art

[0004] As shown in FIGS. 1 and 2, the typical shoes comprise a shoe sole 10 attached to the bottom of a shoe upper 13 by such as the adhesive materials, or by welding processes. The shoe sole 10 includes a recess 15 formed or provided in the upper portion thereof for receiving the bottom portion of the shoe upper 13, and includes a cavity 101 formed therein for receiving a circuit board or one or more batteries or a control casing 11 therein. The control casing 11 includes one or more light devices, such as the light bulbs, or the light crystal displayers, or the light emitting diodes 111 coupled thereto with electric wires 112. The shoe sole 10 should include one or more depressions or recesses formed therein for receiving the light bulbs 111 and the electric wires 112, and should be formed with the cavity 101 therein for receiving the control casing 11. While manufacturing, either of the electric wires 112 is cut off, or either of the light bulbs 111 is disengaged from the position, the shoe sole 10 will be determined as the defective product and should be discarded.

[0005] In addition, the control casing 11 and the electric wires 112 and the light bulbs 111 are solidly received and embedded within the shoe sole 10 and may not be disengaged or removed from the shoe sole 10, such that the light bulbs 111 and the batteries may not be changed with the other ones, particularly the new ones, when the light bulbs 111 and the batteries have been damaged or have been consumed. Furthermore, the control casing 11 and the electric wires 112 and the light bulbs 111 or the other electric parts may be damaged while washing the shoes, because the electric parts may not be removed or disengaged from the shoe sole. The typical, light devices are typically actuated by the typical spring-actuating type switches which will be easily damaged and will continuously energize the light devices inadvertently.

[0006] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional light devices for shoes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0026] Referring to the drawings, and initially to FIGS. 3-5, a shoe in accordance with the present invention comprises a shoe sole 3 including one or more openings 30 formed in the outer peripheral portion and opened outward for receiving the light devices 2 therein respectively, best shown in FIG. 4. The light devices 2 each includes a casing 20 engaged and secured in each of the openings 30, by such as the force-fitted engagement. The shoe sole 3 is normally made of rubber or resilient materials which may suitably clamp the casing 20 and solidly retain the casing 20 within the opening 30 of the shoe sole 3. The casings 20 each includes a peripheral flange 25 extended radially inward from the open end thereof (FIGS. 8, 9, 10), and each includes one or more batteries 27 received therein.

[0027] A circuit board 22 is received in each of the casings 20 and includes one or more light bulbs 24, such as the light crystal displayers or the light emitting diodes attached thereto, and includes a switch portion or a switch member 221 (FIG. 5) or a depress type switch member 231 (FIG. 6) provided thereon. The batteries 27 are electrically coupled to the light bulbs 24 and the switch member 221 (or 231), for energizing the light bulbs 24 and/or the other electric members, such as the buzzers (not shown). A cap 21 includes a duct 23 extended therefrom (FIGS. 8, 9, 10) for engaging into the casing 20, and includes a peripheral rib 26 extended from the duct 23 for engaging with the peripheral flange 25 of the casing 20 and for detachably securing the cap 21 to the casing 20.

[0028] Alternatively, as shown in FIGS. 11, 12, 13, the casing 20 may include an inner thread 70 formed or provided therein, and the cap 21 may include an outer thread 71 formed or provided thereon for threading with the inner thread 70 of the casing 20 and for detachably securing the cap 21 to the casing 20. The circuit board 22 and/or the batteries 27 may thus be engaged into or removed from the casing 20 for changing purposes or the like. It is preferable that the cap 21 is made of resilient and/or transparent or semi-transparent materials for allowing the light emitted by the light bulbs 24 to be emitted through the cap 21. The cap 21 includes a rod 28 extended therefrom. The cap 21 may be formed into various kinds of shapes, such as the heart, the star or the like, or areas or configurations as shown in FIGS. 3 and 5-7. As shown in FIG. 7, the cap 21 may include a height large enough to engage with or to cover a portion of the shoe upper 13.

[0029] A tube 211 is engaged onto and secured to the rod 28 with such as the force-fitted engagement, the adhesive materials, or by welding processes, etc., and directed toward the switch member 221 (or 231) such that the tube 211 may be forced to engage with the switch member 221 (or 231) and to actuate the light devices 24 by depressing the cap 21 (FIGS. 10, 13). The tube 211 is made of electric conductive materials when the switch member 221 includes a configuration as shown in FIG. 5, for electrically coupling the electric circuits of the circuit board 22, and is not required to be made of electric conductive materials when the switch member 221 includes a depress type configuration as shown in FIG. 6.

[0030] It is to be noted that the light devices 2 are not solidly retained within the shoe sole 3 and include a cap 21 that may be disengaged from the casing 20 for allowing the batteries 27 and/or the circuit board 22 and/or the light bulbs 24 to be changed with the other ones, such as when the batteries 27 and/or the circuit board 22 and/or the light bulbs 24 are consumed or are damaged. The light devices 2 may also be disengaged from the shoe sole 3 while washing the shoe sole 3. In addition, the light devices 2 may be engaged into any of the shoe soles, and may be used or actuated independently when the light devices 2 are disengaged from the shoe sole.

[0031] Accordingly, the shoe in accordance with the present invention includes a shoe sole having one or more detachable or changeable light devices and having one or more batteries and/or light bulbs that may be changed with the others or the new ones.
